What else do Google, YouTube, Instagram, Reddit and Spotify have in common besides being some of the world's most popular software services? True: they all use Python.

Python is everywhere. You can not even imagine how wide it is. Most importantly, Python is easy to learn, easy to read and easy to write. It also has a high development speed without compromising reliability or scalability.

Thanks to the high demand for Python, it is well supported and very popular.

But what exactly is Python used for? Which technology or business does Python benefit the most from? If you want to get into any of the following areas, consider whether or not you want to choose Python to develop your technology.

Python for web development

In the current market there may be a business without a website. In addition, this trend is looking for more and more impressive web applications, which include the following:

Perfect mobile and desktop versions
Asymmetric layout
Progressive web applications
Integrated animations
ML chatbots
Today, more than ever, it's important to choose the right tools when building (or possibly rebuilding) your website or web application.

Benefits of Using Python for Web Development

There are many benefits to Python that will help you get great results in web development fast:

1. Python has a large collection of pre-built libraries for almost anything . For example, libraries for scientific computing, image processing, data processing, machine learning, deep learning, etc.

2- Python code takes less time to write due to its simple and clear syntax. Because of this, the code written in Python can build prototypes very well and quickly.

3- Python accelerates ROI of commercial projects. The reason for this is similar to the previous point: you can write and send your code faster. This is especially important for startups.

1. Python has a built-in framework for unit testing. This helps you send bug-free code. In addition to the standard features of Python, one of its most important strengths in web development is the variety of web frameworks offered.

With a wide selection of well-supported frameworks, you can find the right starting point for any project. Python provides you with the tools to do the job with confidence:

Quick and out-of-the-box implementation solutions

Solutions that require the cooperation of many specialized micro services
A program whose performance is very important
Top Python Web Frameworks
Django: Python's most extensive web framework - at least until recently. The Django trademark is complete because it aims to provide all the tools needed to build a web application in a single package. This is a good option if your program is relatively standard, as it allows you to search through the basics and find an efficient solution faster.

Flask: Compared to Django, Flask focuses much more on minor services, which may be the reason for its new No. 1 popularity based on JetBrains. Unlike Django, which is all in one package, Flask works more like glue, allowing you to blend libraries together. Flick throws itself well into a repetitive approach to adding new features and services "once in a while."

Bottle: Bottle is another framework that prefers to ignore the fact that it overshadows the user with anything else it may need. This framework is lightweight and has no external dependencies other than the standard Python library (stdlib). Great for prototyping, as a learning tool, or for building and running simple personal web applications.

Pyramid: Pyramid perfection comes from the legacy of two previous frameworks: Pylons and repoze.bfg.Now, which are now integrated into Pyramid. Pylons was one of Python's top frameworks. The most important advantage of Pyramid over Django is that it is very easy to customize, while Django is more "thoughtful". This makes Pyramid a great choice for non-standard projects that can be more complex.

Python for Internet of Things (IoT)

Depending on your point of view, the Internet of Things can be understood differently. Because of this explanation, suppose we are talking about physical objects in an embedded system that the system connects to the Internet.

These "objects" now have their own IP address and can communicate with other "objects" remotely or locally using the network. The IoT is often involved in projects involving wireless sensor networks, data analysis, cyber physical systems, big data, and machine learning. In addition, IoT projects often involve real-time analysis and processes.

Ideally, your programming language for an IoT project should already be a powerful choice for the above areas, yet light and scalable. Python meets these criteria very well.

Advantages of using Python for IoT

1. The popularity of Python is a significant asset. The language is supported by a large and useful community, which has led to the creation of a large collection of pre-written libraries and easier implementation and deployment of work solutions.

2- Python is portable, expandable and embedded. This makes Python independent of the system and allows it to support many of the computers on the market, regardless of architecture or operating system.

Python is great for managing and organizing complex data. This is especially useful for IoT systems, which are particularly heavy data.

4- Learning Python is easy without forcing you to get acquainted with many formatting standards and options. The most immediate result of this is faster results.

5- Python code is compact and easy to read thanks to its clean syntax. This is useful on small devices with limited memory and computing power. In addition, syntax is partly responsible for Python's growing popularity, and is further strengthening its community.

1. Python's close connection to scientific computing has paved the way for the development of IoT. If a social scientist or biologist wants to create a program for his or her smart device in the lab, they will be happy to use their favorite language. In most cases, this language will be Python, because this technology has become scientific computing.

2. Python is the language of choice for the Raspberry Pi. This is important because the Raspberry Pi is one of the most popular microcontrollers on the market.

3. Python provides tools that simplify the IoT development process, such as webrepl. This option allows you to use your browser to execute Python code for IoT. In addition, the mqtt messaging protocol allows you to update your code or configuration.

4. Because Python is an interpretive language, you can easily test your solution without compiling code or flashing the device. Using a C program, you have to compile the code on your PC, then upload it to your "object". Python allows you to enter directly into the interpreter about your "object", and this experiment makes different solutions easier.

5. AWS provides the Python SDK for AWS IoT. Think of it as a cherry on top of a delicious cake right now.
